Title: Improvements in measuring instruments for determining the height of tall objects
IPC: G01C5/00
Filed: 1958-03-14
Abstract: 858,099. Instrument for measuring the height of tall objects. DAHLBERG, T. O. R. March 14, 1958, No. 8346/58. Class 97(2) An instrument for measuring the height of tall objects, such as trees, consists of two sights comprising a fixed foresight, a foresight on a pivoted arm and a fixed backsight common to both foresights, angularly displaceable relative to each other, and means for recording their angular displacement, comprising a record strip and printing means, said strip being movable laterally by an amount corresponding to the angular displacement of the two sights. As shown, R is a rod of known height, and if angle V1 can be found, the distance between the rod and the instrument B can be calculated, and similarly, knowing the distance and the angle V2, the height h1 can be found. By adding the known height h2 to h1, the height of the tree h can thus be calculated. The angles V1 and V2 can be found, using an instrument B, comprising a fixed fore-sight F, a fixed backsight D, and a fore-sight E fixed on a pivoted arm C. The results are recorded on a strip. which is moved transversely by the arm C, by a rotatable type wheel attached to the instrument case, and the height of the tree can be found from these readings by using tables. A second pivoted arm may be attached to the instrument B, and both arms may have parallelguided jaws so that the instrument can be used to measure tree diameters.

Title: Improvements in or relating to unsaturated polyester resinous compositions
Inventor: HAYES BRENDAN THOMAS
IPC: C08G63/685
Filed: 1959-03-12
Abstract: Unsaturated polyesters are made copolymerizable at room temperature by reacting them with a tertiary mono-amine containing two aliphatic groupings and one aromatic grouping attached to the nitrogen atom, either the aromatic grouping or one of the aliphatic groupings containing a single reactive group as a substituent, the reactive group being COOH, COO-alkyl, NH2 or OH.  In examples, polyesters obtained by reacting phthalic anhydride, maleic anhydride and propylene glycol were reacted with (1) N-2-hydroxypropyl-N-methyl aniline; (2) 3-b -hydroxy-ethoxy diethylaniline; (3) Ethyl-p-dimethylamino benzoate; (4) Methyl phenyl ethanolamine.  The modified polyesters were stabilised with hydroquinone, then benzoyl peroxide was added, and finally styrene was added and the mixture copolymerized.  The modified polyesters may also be copolymerized in admixture with the unmodified polyesters, the benzoyl peroxide being pre-mixed with the latter.  Specification 757,989 is referred to.
